Well, let me tell ya, my hydrangeas, they weren’t doin’ too good. Kinda droopy, not many flowers. Then I heard somethin’ ’bout coffee grounds for hydrangeas. Sounded crazy, but I thought, why not give it a try? I drink a lot of coffee, got plenty of them grounds.
Coffee Grounds for Hydrangeas
So, I started savin’ up them used coffee grounds. Every mornin’ after my coffee, I’d dump the grounds in a bucket. Didn’t take long to get a good amount. Now you need to know how to use coffee grounds on hydrangeas. I don’t know what I did, I just did what I heard.

- First thing, I just sprinkled some coffee grounds around the base of my hydrangeas. Not too much, just a little bit. Like saltin’ your food, you know?
- Then, I kinda worked ’em into the dirt a little with my hands. Didn’t want ’em just sittin’ on top. Gotta get down there with the roots, right?
- After that, I gave ’em a good waterin’. Gotta soak it all in, help it all mix together. And this is how to fertilize hydrangeas with coffee grounds.
Now, I heard some folks say you gotta be careful. Coffee grounds can make the soil too, what’s that word? Acidic? Yeah, that’s it. My hydrangeas like it a little acidic, though. That’s how they get them pretty blue flowers. If you want pink or purple, maybe you don’t need so many coffee grounds.
I kept doin’ this for a while, every few weeks or so. And you know what? It worked! My hydrangeas started perkin’ up. More leaves, more flowers. And them flowers, they were a real pretty blue. Just like I wanted. Coffee grounds make hydrangeas blue! That’s what they say.
More About Coffee Grounds and Plants
I got some roses, too. Heard coffee grounds are good for them, too. They need lots of food, them roses. So I gave them some coffee, too. And they seem to like it. Lots of pretty roses this year.
But, you gotta be careful. Not all plants like coffee grounds. I heard some plants, like, uh, asparagus fern or somethin’, they don’t like it at all. Makes ’em not grow good. So, you gotta be careful which plants you give it to. You don’t want to use coffee grounds on plants that don’t like coffee.
- Coffee grounds can have salt in ’em. Too much salt ain’t good for plants.
- If they’re wet, coffee grounds can get moldy. And mold ain’t good for plants neither.
- And there’s that stuff, caffeine. A little bit’s okay, but too much might hurt some plants. I am not sure about this but that’s what I heard.
So you just gotta use your common sense, I guess. Don’t overdo it. Just a little bit here and there. And if your plants start lookin’ bad, maybe you’re givin’ ’em too much coffee. Just like people, some plants like coffee, some don’t.
I also heard if you want to save your coffee grounds for later, you can freeze ’em. I do this sometime when I got a lot and don’t need it right then. This way you can use coffee grounds when planting hydrangeas in the early spring.
My Hydrangeas Love Coffee
But I tell ya, I’m gonna keep givin’ my hydrangeas coffee grounds. They sure do love it. And I love them pretty blue flowers. It’s like a little bit of magic, turnin’ old coffee grounds into beautiful flowers. It is cheap and easy to fertilize hydrangeas with coffee grounds.

So, if your hydrangeas ain’t doin’ so good, maybe give coffee grounds a try. Just remember what I said. Not too much, and make sure you water ’em good. And maybe, just maybe, you’ll get some beautiful blue flowers, too. It’s worth a shot, ain’t it? I think all the hydrangeas like coffee grounds. Just give it a try.
Now, I ain’t no expert. I just know what works for me. And coffee grounds, they work for my hydrangeas. So, that’s all I gotta say about that. Maybe you will be happy you use coffee grounds for hydrangeas. Go try it now!
